SGM Modbus RTU Gateway

Sepehr Modbus RTU Gateway is an innovative solution in the field of industrial IoT (IIoT), it gathers data from industrial equipment and environmental monitoring sensors, securely transmitting them to your customized SCADA system or advanced monitoring software through a standard LAN connection using the SNMPv3 protocol. Within the system, the Modbus RTU protocol is used exclusively to establish communication between the sensing and measuring devices and the central modbus gateway.

What is Modbus and How Does it Work?

In the Master/Slave Modbus protocol, data is transmitted in tables and only the Master device (the gateway) requests data from the Slave devices (Sepehr environmental sensors), meaning other devices cannot send data without the Master’s permission.

The most common type of this protocol is Modbus RTU, in which a single Master gateway and multiple Slave devices are connected in a network over a bus topology. In this setup, each device is linked sequentially to the two neighboring sensing or industrial equipment except for the first and last devices in the chain.

In this system, the Sepehr Modbus Gateway operates as the Master, while the environmental monitoring devices and other industrial equipment function as Slaves. Each Slave is assigned a configurable Slave ID, which can be manually set (e.g., via binary switches). This ID allows the data sent by each device, such as temperature readings, to be clearly identified and correctly matched to the right Slave by the Master.

Industrial Automation with the Modbus RTU Gateway

The Sepehr Modbus Gateway is a robust device designed to receive data and control environmental conditions in industrial and sensitive spaces. It can simultaneously collect data such as temperature, humidity, water leakage, and power status from up to 30 sensors and securely transmit this information to servers or specialized software, such as SCADA or the Sepehr Monitoring System.

Thanks to its easy installation, simplified wiring, and wide coverage, this gateway is an ideal solution for factories, server rooms, data centers, large greenhouses, cold storage facilities, industrial warehouses, power stations, and telecommunication sites.

The instant SMS alerts and secure data transfer keep you informed of any issues or disruptions in real time.
